B: now dealing with the touch DNA samples.H if a person touches something the material on your hands can be transferred
B- its the lockart principle - every contact leaves a trace? H correct
B if I correctly understand, you placed the knife on the bed? Correct? H I did it personally to swab
B: but what about the bed it is lying on? Could that not transfer material? Why place it on the bed?
(Good point made by Botha but this applies also to the blunt axe having struck the assailant's shoulder in the tussle with HvB. There must be blood and fibres from a stranger?)
